device for optimizing the performance of a filter in the rotating drum, in particular for filtering liquid with high percentages of suspended solids

摘要

a device for optimizing the performance of a filter in the rotating drum (4) prerivestito, especially for filtering liquids with high percentages of suspended solids.includes a knife or blade (39) act to remove from said drum (4), a layer of fibre that is more strongly all effect of solids held during the filtraggior, said drum (4) rotating above a tank (2) in which is contained a liquid (3) from the filter, said drum (4) being partially immersed in the liquid (3).the level of the latter present within the tub comes up to a level (l), compared to the drum (4) less than two thirds of the radius (r) of the latter.the upper floor of the tub (2) are always parallel with a floor support (25) of the filter in the rotating drum (1).
